Don't really have an answer, but to help with info for everyone else. The 32 bit data represents number of seconds since reset and turned on. So if you started it on Jan1, 2010 at midnight, the counter would be 86,400 on Jan2 at midnight.

So divide the answer by 86400 for number of days
divide the remainder by 3600 for number of hours
divide the remainder from that by 60 for number of min
remainder is seconds

now getting the date is another story. I have no idea how to account for 28,30 and 31 days in the months to be able to convert the number of days into an actual date
